UserManager value is null for first time to the function FindByNameAsync()

Question

User1389134248 posted

var userManager = context.OwinContext.GetUserManager<ApplicationUserManager>();
var user = await userManager.FindByNameAsync(context.UserName);

I have got the value in context.UserName and the same username exists in DB. But FindByNameAsync() function returning null sometimes for the first call.

if I call the same function again it is giving output as expected. when I call it as in the below code.

if(user == null) {

var user = await userManager.FindByNameAsync(context.UserName);

}

Can anyone help me out of this?

Many thanks in advance.

Note: It's not happening every time but happening quite often.

After a successful login the username is located in the current ClaimsPrincipal.

string user = User.Identity.Name;

Hi bbratnam,

Commonly, we get Username like below:

string username = Context.User.Identity.GetUserName();

Or:

string username = Context.User.Identity.Name;

With above code, it's hard to tell where is the problem.

Here i'll provide some examples about FindByNameAsync() you can refer to: FindByNameAsync().

Best Regard,
